CAR-COUPLING.

f0 aZZ whom, zit may concern/.-

Be it known that I, \V. J. BROWN, of \Vebster City, county of Hamilton, State of Iow.., haveinvented a new and Improved SelfActing CarCoupler for Railroad-Oars, of which the following is a specification.

The invention relates to that class of car couplings in which an arrow-head link is used to press open one or two spring'jaws which then fall in behind the head.

Figure l of the drawings is a longitudinal vertical section showing the link held; Fig. 2, a plan view; Fig. 3, a longitudinal section showing the movable jaw held up; and Figs. 4 and 5 are perspective views of the jaws removed from the draw-head.

In the drawings, A represents the drawhead, B the movable jaw, and C the fixed jaw. D is the link, having heads (2 cl at the ends. Eisa cam on ashaft, c, which is tui ned by a hand-lever, E, to lift the spring F, which carries the movable jaw B. The lever E has a spring, 0, fastened thereto and end slotted at the free end, so as to press against the keeper orguide c, and thus hold the jaw B up or down.

The jaws B G are peculiarly constructed, so as to enable them to perform their functions to the best advantage, and not to be liable to get out of order.

The jaw B has a solid part, b, an opening, b, through which the link-head passes, an open top slot, b, across which is arranged the pivot for spring F, and a rear projection, b, by which the link-head is raised in uncoupling.

The jaw G has an upper tenon, 0 on which the jaw B slides, and which works in the aperture I). c 0 are shoulders or stops for the (No model.)

sliding jaw B to rest upon when pressed down by spring F. c is a front flange at the bottom to fit under the part a of the draw-head, and c is a hole through which passes a screwbolt fastening, 0. The draw-head is suitably grooved to receive thesejaws and has a cavity, G, behind them for the linkheads.

The jaw B in its upward movement is liable to cramp and jam in the grooves of draw-head when lifted by an arm which necessarily moves in the arc of a circle. to overcome this tendency, I use a spring-arm of flat elastic metal and having an eye, f, at the front end, so that the eccentricity of the motion of jaw B and arm F will be taken up mainly by the yield of the spring. The spring arm thus performs two functions in uncouplii;igna1nely, to raise the jaw and to neutral ize the eccentricity of its own motion.

Having thus described all that is necessary to a full understanding ofmy invention,what I claim as new, and desire to protect by Letters Patent, is

1. The sliding jaw B, provided with open ing 1) and rear projection, b, in combina' tion with a fixed jaw, 0, having tenon c and shoulders c 6-, whereby said jaw in rising not only unlocks itself from the link but also the fixed jaw by carrying the link-head up above said fixed jaw.

2. The combination of a draw-head having keeper 0', the lever E, carrying spring a near its handle end, and the shaft 6, carrying cam E, with the slidingjaw B, as and for the purpose specified.
